We present the results on elliptic flow with multi-strange baryons produced in Pb-Pb collisions at = 2.76 TeV. The analysis is performed with the ALICE detector at LHC. Multi-strange baryons are reconstructed via their decay topologies and the v (2) measurements are analyzed with the two-particle scalar product method. The p (T) differential v (2) values are compared to the viscous hydrodynamical (VISH2 1) model calculation and to the STAR measurements in Au-Au collisions at = 200 GeV. We found that the model describes a parts per thousand and Omega v (2) measurements within uncertainties. The differential v (2) of a parts per thousand and Omega is similar to the STAR measurements at 200 GeV in Au-Au collisions.
